Sediment  data  posted  on  page

Second  spreadsheet  for  yesterday  added  to  page

The  EPA  sediment  samples  collected  in  the  Animas  River  from  Bakers  Bridge  to  north 
of  Durango  have  been  validated.  EPA  has  done  a review  of  the  data  which  included  a 
comparison  to  background  to  determine  if  the  metal  concentrations  are  consistent  with 
pre-incident  levels.  Metal  results  that  exceeded  pre-incident  levels  were  subsequently 
compared  to  risk-based  screening  levels.  These  results  indicate  that  minor 
exceedances  of  background  concentrations  were  observed  for  antimony,  lead,  silver, 
thallium.  However,  comparison  to  risk-based  screening  values  found  these 
exceedances  to  below  risk  screening  levels.  The  review  and  interpretation  of  these  data 
was  a collaborative  effort  that  included  state  and  local  members  of  the  unified 
command.
